* When configuring a block instance, "Turn editing off" button is not
shown anymore.
* When configuring a block instance, the breadcrumbs are now better,
providing a link to the course page. This could be done in a much
better way if we had a comprehensive template system but it will
suffice for now.
I hope this time I got everything changed to the new Page interface! I 'm
really sorry for messing up and breaking new installations... :(
Also moved the only two functions of the API outside the page_base class.
NEW: The code now supports dynamically plugging your own Pages and block position
identifiers into Moodle without messing with the main libraries at all.
UPDATE: Many functions in blocklib now use pass-by-reference for speed.
UPDATE: Class MoodlePage has been made more presentable and robust.
--------------
Brand-new pagelib.php at your disposal! It slices, it dices, it makes your coffee.
It still doesn't understand women... Read the comments in pagelib.php for a first
impression. Feedback highly encouraged!
Blocks code has undergone significant changes to work with Pages. Flexibility is its
middle name, since I think (without having tried it) that adding e.g. a third
placeholder for "center" blocks in courses, with full support for moving around etc,
will now take about 15 lines of new or edited code. If you are not impressed yet, I
suggest watching a documentary on solar physics. :P
MINOR CHANGES:
--------------
Added instance_allow_config() in the blocks class hierarchy to supplement per-instance
configuration options. You can override it to return true and thus get configuration
amenities without allowing multiple instances.
Minor polishing to comments and documentation (whatever caught my eye was game).
Tightened up some code here and there by utilizing all the new features.
BUGFIXES:
---------
A bug in restore_execute.html caused hidden blocks to not be restored at all.
